INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed July 1, 1908. Serial No. 441,330.

To all whom it may concern:

Be it known that I, ERNEST FREDERICK' SICKEN BERGER, a citizen of the United States, residing at Carlstadt, in the county of Bergen and State of New Jersey, have invented new and useful Improvements in Internal- Combustion Engines, of which the following is a specification.

This invention relates to internal combustion engines and has for its object to provide in connection with a four-cycle engine means for increasing the flexibility, power and speed. of the engine and also the control of the engine whereby a full charge of compressed mixture is admitted to the explosion chamber of the engine at each active stroke enabling all speeds of the engine to be controlled by simply manipulating the throttle valve. The arrangement hereinafter described also provides for a prompt acceleration of the speed of the engine by means of the throttle independently of the usual spark leadin ition devices.

Wit t e above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanfying drawings :Figure 1 is an elevationo an internal combustion engine, partly in section, showing the invention ap lied thereto. Fig. 2 is a longitudinal sectlon through one of the fans. Fig. 3 is a cross section through the fan.

Referring to the drawings, 1 designates the cylinder of an ordinary four-cycle internal combustion engine while 2 designates the intake valve and 3 the exhaust valves thereof. I

In carryin out the present invention, a compression an 4 is located in the intake pipe 5 leading from the carbureter 6 to the lntake valve chamber 2, while exhaust fan 7 is arranged in the exhaust connection or pipe 8 leading from the exhaust valve chamber outward to the atmospgere. The fans 4 and Its 9 and 10 respec- 7 may be driven by pulleys 11 on the entively, passing aroun gine shaft 12 and and enables the cylindrical walls around other pulleys 13 and 14: on the'shafts of the fans 4 and 7 respectively.

Each of the fans 4 and 7'is preferabl of the rotary type as best illustrated in igs. 2 and 3, each fan comprising a substantially cylindrical fan casing 15 provided with tangentially disposed and oppositely arranged nozzles 16 and 17 while the fan itself comprises a rotary shaft 18 and a series of radially disposed blades 19 in the rotation of which the air or the mixture or exhaust gas is drawn in through one of the nozzles 16 or 17 and expelled through the other nozzle. It'will also be observed that both fans are oppositely driven by the engine without the aid of any extraneous devices.

By means of the construction above described, it will be seen that a full charge of gas and air under compression is forced into the explosion chamber of the engine for each active stroke thereof, which is a particularly valuable feature when the engine .is

running at hlgh speed as it gives increased power to the engme as compared with the en 'ne now in common use in which, as is we known, only a partial charge is ad mitted to the cylinder. This increases the flexibility, power and speed of theen e the same to be quickly contro led by means of the throttle, although, it is, of course, to be understood that the usual spark advancing and retarding mechanism may alsobe used in connection with the'engine.

I claim The combination with a gas en e, of rota fans comprising cylindrical ancasings aving inlet and outlet connections in thereof, said casings being interposed in the intake and exhaust lines of piping connecting with the engine, fans mounted in said casings,'and driving wheels on the fan shafts receiving driving belts from a rotary element of the engine.

In testimony whereof I aflixmy signature in presence of two witnesses.

I ERNEST FREDERICK SIGKENBERGER.
